So I picked up a Henry 44mag/spl rifle. I slugged the barrel, came up with .4312.
So I ordered a .432 sizer insert for my lee App press.
The bullets are dropping at .4321 from my friends NOE mold, and are measuring .4331 after powder coating. measuring on the lube groove area.
After sizing I am getting some odd numbers. the lube groove area is coming out at .4317. The bases are gas checked, and are coming out at at .4323.
I understand copper will spring back a little after sizing. The numbers just don't seems to add up to me. how is the body winding up 0.006 smaller than the base?
